Sirius CRM vs HubSpot Free 2026: Which Free CRM Is Better for B2B Sales Reps?

HubSpot Free is famous for being "free forever" with unlimited users and contacts. But is it really the best free option for B2B sales reps in 2026? In this comparison, we analyze the two most relevant CRMs with free plans for the B2B market.

The short answer: it depends on what you need. The detailed answer is below — with honest pros, cons, and the limits neither platform advertises on their "free" banner.

HubSpot Free vs Sirius CRM FREE: Direct Comparison

Does HubSpot Free Have WhatsApp Integration?

No. HubSpot CRM Free does not have native WhatsApp integration. The platform offers communication channels like email and live chat, but there is no direct WhatsApp Business connection. To integrate WhatsApp with HubSpot, you need HubSpot Marketplace apps (usually paid) or Zapier automations.

Is the 100-Deal Limit of Sirius CRM FREE a Problem?

For most individual sales reps and small teams, no. An active B2B salesperson rarely has more than 30 to 40 deals in simultaneous negotiation. Closed deals (won or lost) do not count toward the active limit. In practice, 100 active deals is sufficient for most individual reps and teams of 2 to 4 salespeople.

When the business grows and the limit becomes a real obstacle, upgrading to Sirius PRO removes all limits and adds advanced AI and prospecting features.

When to Choose HubSpot Free?

HubSpot Free makes sense if you:

• Have a large team (20+ salespeople) and need scalability at no extra cost
• Operate in an international market and need the interface in English or Spanish
• Plan to use the full HubSpot ecosystem (Marketing Hub, Service Hub)
• Use email as the primary prospecting and follow-up channel
• Do not rely on WhatsApp as a sales channel

When to Choose Sirius CRM FREE?

Sirius CRM FREE is the right choice if you:

• Are a B2B sales rep, field salesperson, or freelance sales professional
• Use WhatsApp as your main client communication channel
• Want AI lead qualification without paying for it
• Work in the field with unreliable connectivity
• Want a simple CRM that is fast to learn
• Have up to 100 simultaneous active deals

FAQ: Sirius CRM vs HubSpot Free

Does HubSpot Free have a contact limit?

No. HubSpot CRM Free allows unlimited contacts and users — that is one of its main free-plan advantages. The limitations are in features: no automations, no advanced reports, no email sequences, no AI. To access those features you need to upgrade to paid plans (Starter, Professional, Enterprise), which are priced in USD.

Does Sirius CRM FREE have any hidden limitations?

The main limitation is the maximum of 100 simultaneous active deals. Won or lost deals do not count toward the limit. In addition, AI is limited to 3 generations per month on the free plan (unlimited on PRO) and integrations with external tools are more limited. There are no surprise charges or credit card requirements.

Which free CRM is easier to use for someone who has never used a CRM before?

For someone with no prior CRM experience, Sirius CRM has a lower learning curve. It was built for simplicity — for the field salesperson, not a revenue operations team at a global enterprise. HubSpot has many more features even on the free plan, which can be confusing at first.
